Lottery is a form of gambling in which people purchase chances to win money or other prizes. Prizes are typically awarded on the basis of a random drawing. Unlike most forms of gambling, lottery proceeds are generally not taxed and may be used for any purpose. The casting of lots to make decisions or determine fates has a long history in human society, including the biblical story of Job; however, the lottery as a way of raising funds for public projects is of much more recent origin. State-sponsored lotteries began to appear in Europe in the 1500s, although many earlier private lotteries were based on the casting of lots.
The modern state-run lotteries operate a similar pattern: the state legislates a monopoly for itself; establishes an agency or public corporation to run the lottery (as opposed to licensing a private firm in return for a share of profits); starts operations with a modest number of relatively simple games; and, under pressure for new revenues, progressively expands the lottery in terms of game complexity and prize amount. This expansion has fueled concerns that the lottery is inefficient and that it promotes gambling among the poor, problem gamblers, and young people.
While the state may claim that lottery proceeds are used for the benefit of the general public, the reality is far different. Most state-run lotteries are heavily dependent on specific constituencies: convenience store operators, whose sales are the primary source of lottery revenue; suppliers, whose contributions to state political campaigns are often substantial; and teachers, in those states where a portion of the proceeds is earmarked for education. These interests have been able to keep the lottery popular even in the face of state budget deficits, as well as during periods of economic prosperity when it might otherwise have been abolished.
Most state lotteries are little more than traditional raffles, with ticket holders purchasing chances to win a specified prize in a drawing at some future date, usually weeks or months away. Some state lotteries offer instant games, which have lower prize amounts and higher odds of winning, but these are increasingly less common. Revenues typically increase dramatically in the first few years after a lottery is introduced, but then level off or decline as players become bored with the limited selection of available games. To counter this “boredom factor,” lottery managers constantly introduce new games, hoping that a fresh novelty will reinvigorate the player base and raise revenues again. This reliance on consumer demand is in sharp contrast to the original argument made by state lawmakers that lotteries are valuable as sources of “painless” revenue. State politicians regard lotteries as a way to collect taxes without forcing voters to raise their own income taxes, and the popularity of the lottery has grown as popular antitax movements have led lawmakers to seek alternatives to conventional tax revenue. Lottery supporters also argue that the popularity of the lottery proves that people will always be willing to spend their money on a chance to win.
